publicized the whole source code of Android and Linux. The good point is that, platform owners can save a great amount of time and energy developing and maintaining the platform, because 3rd party developers will do this for them. With less money spent on development and maintenance, a relatively low price can attract more and more phone users. Contrarily, closed platforms lock their source code in the safety and forbid 3rd party accesses. Apple and Microsoft are the representatives of them, they are both closed sourced, but some differences do exists. 3rd party iPhone applications are restricted within narrow limits, for that Apple will look through every application which is uploaded onto ‘App Store’, and a lot of applications are turned don’t c heck Windows applications at all, it all depends on the users themselves. You installed the mareware, you suffer the loss. . Application Market Market is the medium between developers and users, hence it’s very important. Some predicted that there will be more and more application markets while some don’t think so. In current markets, both do exist. Some specify only one market for their products, while others sell their softwares in various markets. Softwares from Nokia, Microsoft and Linux Mobile are sold in every market. Developers of these platforms can release their own application in whatever markets, so markets have to pete with each other for a living. This is good for users. However, the lack of universal management may lead to mess and chaos, softwares that have the same functionality exist in different markets, which confuses users a lot. Correspondingly, sole markets claim that most applications should be sold in them. This kind of monopolization leads to no petitor. ‘App Store’ and ’Andr oid Market’ are deputy of sole markets. Normally, iPhone applications can only be found in ‘App Store’, and Apple will check every one of them by itself. Good news is that every application in ‘App Store’ is officially tested, it’s safe。 Bad news is that a lot of pretty good softwares are rejected for various reasons. And a big unofficial mechanism is built by hackers, that is ‘jailbreak’ and ‘SIM unlock’. ‘Jailbreak’ is a process that allows iPad, iPhone and iPod Touch users 河北大学 21012 届本科毕业生外文文献翻译 7 to gain root access and unlock the operating system thus removing any limitations imposed upon them by Apple. Once jailbroken, iPhone users are able to download many extensions and themes previously unavailable through the App Store via installers such as Cydia. A jailbroken iPad, iPhone or iPod Touch is still able to use the App Store and iTunes [9]. And a ‘SIM lock’ is a capability built into GSM phones by mobile phone manufacturers. Network providers use this capability to restrict the use of these phones to specific countries and work , phones can be locked to accept only SIM cards based on the International Mobile Subscriber Identity. ‘SIM unlock’ make it possible to use a mobile phone without considering countries and works specified by mobile phone manufacturers. However in Android, Google doesn’t test every application at all, so although there’s an official market for Android applications, you can still release your product anywhere you want. Considering security problems, Google banned the use of some ponents. Like ‘jailbreak’ and ‘SIM unlock’ in iPhone, ‘root’ in Android gives users 100% control of their devices, along with some security risks. ‘Root’ is a process that allows users of cellphones running the Android operating system to attain privileged control (known as root access) within Android39。 s Linux subsystem, similar to jailbreaking on Apple devices running the iOS operating system, overing limitations that the carriers and manufacturers put on such phones. Rooting makes it possible to use custom versions of the Android system such as CyanogenMod, supporting features unavailable in stock ROMs. It also allows for newer versions of Android not supplied by the original device manufacturer. In contrast to iOS jailbreaking, rooting is not needed to run applications not distributed by the official Android Market. It is needed however, when trying to access paid Android applications from countries which are not part of the paid applications market. . Integration Some panies focus only on their core industry, . develop an operating system and provide an environment for 3rd party development. Others not only do these, but manage the process of developing a software to publicizing it. Depending on the integration of platforms, we sort them to 4 kinds: full integration platform, market integration platform, device integration platform and no integration platform. The publicizing model of full integration platform is very strict. Its 河北大学 21012 届本科毕业生外文文献翻译 8 management ranges from device manufacturing to application release, whose representative is Apple. Apple’s factory produces iPhone, Apple’s ‘App Store’ sells application, Apple’s ‘iTunes’ is the channel of Apple’s resources. The whole process is under Apple’s control. Market integration platforms mit themselves to developing and selling softwares. Google is one of them. Unlike apple, Google don’t have a factory to manufacture its own handsets, but only developed Android and set up ‘Android Market’ for Android applications. However, panies like Google definitely have the capability to produce its own devices. Google is in good relationship with HTC, who is the OEM of TMobile, O2 and Orange, etc. Device integration platforms produce their own handsets, but don’t set up application markets. Forexample, RIM makes Blackberry, but there’s no official application market for Blackberry. No integration platforms do few things. Microsoft neither makes mobile phones, nor sets up a they do is only developing the oper。
